High performance liquid chromatograph (HPLC) detectors pass a beam of light through a column effluent as the fluid passes through a low-volume flow cell. Variations in light intensity are recorded and a chromatograph is generated.

Bolt tensioners are used in place of standard hex nuts or bolts for easier and more precise tightening of large-diameter bolt and stud assemblies. They are sometimes called multi-jackbolt tensioners (MJTs).

Surface tension and wettability instruments measure fluid surface tension, a tangential force that keeps a fluid together at the air/fluid interface. Surface tension is a direct indicator of the quality of any chemical and any formulation.

Motion detectors are devices that contain either a physical mechanism or an electronic sensor that detects motion within a specific field of view. Common motion detectors include passive infrared (PIR) and active ultrasonic and microwave.
